ASME B16.10 VALVE FACE TO FACE & END TO END DIMENSIONS
What is the face to face dimension of a flanged ball, globe or gate valve? The ASME B16.10 chart answers this question, as it standardizes the distance between the inlet and the outlet of the most common flanged valves. The purpose of this ASME specification is to ensure the interchangeability of valves produced by different manufacturers.
Upon request from industry and government, ASME has been defining piping safety since 1922.
This Standard covers face-to-face and end-to-end dimensions of straightway valves, and center-to-face and center-to-end dimensions of angle valves. Its purpose is to assure installation interchangeability for valves of a given material, type, size, rating class, and end connection.
This Standard is to be used in conjunction with equipment described in other volumes of the ASME B16 series of standards as well as with other ASME standards, such as the Boiler and Pressure Vessel Code and the B31 Piping Codes.
Careful application of these B16 standards will help users to comply with applicable regulations within their jurisdictions, while achieving the operational, cost and safety benefits to be gained from the many industry best-practices detailed within these volumes.
